Tool Steel

Welcome to Insaco. Thank you for visiting!

Since 1947, we have been a precision machining and polishing fabricator of parts from all technical ceramics, sapphire, glass and quartz. We machine these materials to very precise tolerances (many times measured in millionths of an inch) for dimension, flatness, wedge and roundness or cylindricity. Our customers typically have a critical application that requires extremely tight tolerances in ultra-hard materials. We also have the capability to grind and polish spherical radius parts in a variety of hard materials, both inside and outside diameters, to optical requirements.

Please feel free to navigate to other pages within our site to see more information on all of our high precision machining services, materials and capabilities. If you would like more information please click here to send a request, or visit our Frequently Asked Questions page.
